STACK-FORM ER.

SPECIFICATION forming part of Letters Patent No. 649,051, dated May 8,1900. Application iilod January 22,1900. Serial No. 2,398. (No model.)

To all whom it may concern:

Beit known that I, JOSEPH A. HAMMAN, of

Bement, in the county of Piatt and State of.

Illinois, have invented a certain Improved Stack-Former to be Used withWind-Stackers, of which the following is a specification.

This invention comprises a straw-barrier attached to the tube of awind-stacker and adjustable with relation thereto to an extent` toenable the side of the stack farthest from the thresher to be positivelyoutlined and colnpactly built. It is exemplified in the structurehereinafter described, and it is defined in the appended claims.

IVind or pneumatic stackers are built tol swing both laterally andvertically, and they are provided with adjustable hoods on theirvdischarging ends, by means of which the di-y rection taken by thedischarged straw may be controlled. They are also usually madeextensible, so that their discharge ends mayv be at different distancesfrom the thresher at the will of the operator; but while they arecapable of directingthe discharge of the straw quite completely theyfall short of building perfect stacks on account of the fact that afterf the straw leaves the stacker it is beyond the control of the`operator, the far side of the stack is formed loosely andunsymmetrically,

of my invention, and Fig. 2 is a side elevation of the same.

A laterally and vertically swingable section of a wind-stacker tube isshown at 1, at 2 is shown a telescoping extension of the tube, and anadjustable hood on the discharge end of the stacker-tube is shown at 3.These elements are well known to stacker-men. ,They

tube in front of the discharge end thereof, whereby the straw may beconfined in the limits described by the swing of the plate, and thestack may be firmly and symmetrically shaped by sliding action of theplate. C0n= sidered specifically, the barrier-plate9 has its verticalends 9 turned outward or away from the thresher, so as to form inclinesthat run freely against the straw asv the plate is swung from side toside and pack it in place. Lugs S are fastened to the upper edge of theplate, near the ends thereof, and they form pivotbearings for the armsthat support the plate. The arms or rods comprise rods 6, which arepivotally connected with lugs 8, tubes 5, into which the rods areextended, and larger tubes 4, which receive tubes 5 and which arepivotally connected one with each side of the slidable section of thestackertube. The tubes 5 are preferably fastened permanently in thelarger tubes 4, while the rods are held adjustably in the tubes 5 bymeans of setscrews, one of which is shown at 3l in Fig. 2. Strips 10 arefastened to the inside surface of the plate 9 under lugs 8, rings l2 areslipped yover tubes 5 and rods 6, and iiaps 11 of iexible material arefastened tothe strips and to the rings. The Iiaps are triangular inoutline, they terminate in acute angles adjacent to the discharge end ofthe stacker-tube, and form guides to conduct the straw toward thebarrier-plate. Clamp-rings 14 are secured on tubes 5v near the ends oftubes 4, they are connected with the tubes by means ends of the flapswith the collars. Bars 25 -are fastened to the rear or outer surface ofthe v pivot of the plate, and are provided with lines 26 and 26h, whichconverge toward the lthresher and merge into a single line 26. The Iiaps1l connect with the plate below the pivot thereof, and the springs tendto pull the lower edge of the plate toward the thresher. The lines 26nare attached to the plate above the pivot thereof, and a pull thereontends to swing the lower edge ofthe plate away from the thresher, and sothe lines and the springs provide means whereby an operator mayinanipulate the lines to vary the position of the plate with relation tothe vertical.

Scl

'of set-screws 15 and springs 13 connect the IOO Means is providedwhereby the plate-carrying arms may be raised or lowered on theirpivotal connections with the stacker-tube. Such means may vary to suitdifferent requirements; but I prefer to employ the mechanism shown inthe drawings, wherein a rocklever 17 is mounted pivotally on the frontend of the slidable section of the stackertube and is connected with thearms that support the barrier-plate through rods 16. An are-formed rack22 is placed adjacent to the rock-lever, a pawl 23 is pivoted in thelever in position to engage the rack, and a line 211 is connected withthe pawl and run over a bearing in the upper end of the lever. The leverhas a clamp-finger 27, betweenwhich and the lever line 2G is ordinarilyheld, and a rope 21 extends from the upper end of the lever to a drum19. The drinn is journaled in a frame 1S, which is fixed on the frontend of the section 1 of the stacker-tube, and it has a crank-handle 20,by means of which it is turned.

rlhe rack and the lever may be attached to old stackers by means ofclamp-straps 28, which in this instance are made each in two parts,which are bolted together and to the rack 22. A bar 30 may be boltedbetween the upper conjunctions of the clamp-straps `to form a pivot forthe rocklever 17, and side bars 29 may be .fastened to the sides of theclamp-straps and provide pivots for the side tubes 4.

The specific means used to attach the stackformer to the stacker-tubewill vary to suit the different styles of stackers, and it is of littleconsequence so far as the principle of my invention is concerned. Thebarrier-carrying arms are to be connected with the slidable section ofthe stacker, and there are "many ways in which this can be effected; butit is essential that the connection shall `be near the rear end of theslidable section of the stacker, so that the barrier-plate may be raisedand lowered to the desired extent with relation to the discharge end ofthe stacker-tube without swinging materially toward or from a verticalline drawn through such discharge end.

In operating the device the rods 0 are adj usted in tubes 5 to snit thesize of stack in' contemplation, and the clamp-rings 111 are shifted andset to give proper tension on springs 13. The drum is turned until therope is wound up sufficiently to take the weight of the barrier-plateand the arms off the pawl 23, line 24 is pulled to carry the pawl out ofengagement with the rack, and the rope 21 is run out until thebarrier-plate is near the ground, when the stacker-tube is in its lowestposition. Then the shiftable section of the stacker-tube is extended bymeans of the mechanism with which stackertubes are provided or anysuitable means, and the line 26 is pulled back until the plate 9 isapproximately vertical and then hitched to the rock-lever. The hood ofthe stackertube is then adjusted to throw the straw toward thebarrier-plate7 and the stacker is swung from side to side until the farside of the base of the stack is built to near the height of thebarrier-plate. "lVhcn this is done, the plate is raised, thestacker-tube is shortened, and the stack is brought up to the outer lineof the base. Then so much has been accomplished, the barrier-plate ismade to slightly overlap the far line of the stack. is adjusted withrelation to the vertical, and another layer of stack is completed in themanner described. This is continued until the stack approachescompletion, when the plate is permitted to slant toward the thresher, soas to properly round oli? the stack.

The crank-handle of the drum is in easy access of an operator on thethresher, and the rope 2l may be run out or taken up to permit thesection 2 of the stacker-tube to slide freely on section 1. The rope 2land the line 24 have nothing to do while the stacker is in operation,and as a matter of convenience the line may be run onto the drum withthe rope, provided sufficient slack is given to preclude the detachmentof the pawl byV action of the drum. The line 26 is preferably heldcaught on the rock-lever g but it may extend to the vicinityof the drumfor convenience in manipulation. In this case the drum is attached to aband used to sustain the section 1 of the stacker-tube, andas this bandis not so very strong a pair of braceplates BlfL are made to extend fromthe band and bear against the upper surface of the tube. These platestake the stress of the rope when the barrier plate is sustained therebyand aid the band in carrying the load.

The 'flaps 11 form lateral guides, between which the straw is directedagainst the barrier-plate.
